New to the forum, just wanted to poke my head in here and see if I could get a question answered.

While I love Steel Panthers, it seems that the mega-campaigns and the original game have been out for a long, long time. Why is it priced at $70, whereas normal PC game releases are about $60? I understand the mega campaigns were more than likely a ton of work, but the pricing has kept me from diving in. The page even says it was released in 2000... Why is a 12 year old game with additional content $70?
